Parr Instrument Company 4570 HP/HT Pressure Reactors PREFACE Scope General Specifications These instructions describe the installation, operation and maintenance of Parr Series 4570 HP/ HT Pressure Reactors offered in two sizes, 1.0 and 1.8 L. They cover the basic steps to be followed when installing these reactors and describe the function of all standard components. They are intended to be used in conjunction with several related instruction sheets listed on the previous page.
Parr Instrument Company 4570 HP/HT Pressure Reactors PREFACE (Continued) Explanation of Symbols II On position, full power heater switch I On position, half power heater switch O Off Position ~ Alternating Current (AC) This CAUTION symbol may be present on the Product Instrumentation and literature. If present on the product, the user must consult the appropriate part of the accompanying product literature for more information. This CAUTION symbol indicates that the surface may be hot.
Parr Instrument Company 4570 HP/HT Pressure Reactors PREFACE (Continued) for that design. But in order to preserve the validity of these designs, all temperature and pressure limits must be observed, and no attempt should be made to increase these limits by making alterations or by substituting components which are not recommended by Parr Instrument Company. 2.
Parr Instrument Company 4570 HP/HT Pressure Reactors INSTALLATION Pressure and Temperature Limits The working pressure and temperature at which any reactor or pressure vessel can be used will depend upon the design of the vessel and the materials used in its construction. Since all materials lose strength at elevated temperatures, any pressure rating must be stated in terms of the temperature at which it applies.
Parr Instrument Company 4570 HP/HT Pressure Reactors ASSEMBLE THE REACTOR Once the bolt is loosened, rotate the housing the required amount, connect the upper shaft to the magnetic stirrer and then tighten the motor housing bolt. These reactors require at least 10 sq. ft. of workspace in a well-ventilated area with convenient access to an electric outlet, running water, air and a drain. 1. Set the stand in the workspace. 2B. Fixed Head Reactor. 2A. Removable Vessels.
Parr Instrument Company 4570 HP/HT Pressure Reactors The Parr Cooling output connector is to be used only with Parr Instrument Company cooling solenoid valve assemblies supplied with the appropriate cooling power cord. ASSEMBLE THE REACTOR (Continued) The pneumatic package includes a pressure regulator with gage located inside of the support stand housing. It can be accessed by removing the back panel of the support stand. The regulator has been preset to 50 psi.
Parr Instrument Company 4570 HP/HT Pressure Reactors ASSEMBLE THE REACTOR (Continued) 10. Note the voltage and amperage requirement stamped on the controller data plate, and then plug the power cord into an appropriate outlet. Power for these reactors should be drawn from a grounded outlet capable of carrying up to the full current rating of the reactor. 6. Connect the thermocouple and extension wire to both the thermocouple and to the controller in the “Primary Temp Input” position on the rear panel.
Parr Instrument Company 4570 HP/HT Pressure Reactors IDENTIFY THE VALVES Gas Inlet Valve Liquid Sampling Valve The gas inlet valve is easily identified when the bomb is open by noting that it is connected to a dip tube that extends to a point near the bottom of the cylinder. This valve has an attached fitting which provides a socket for attaching the A506HC pressure hose furnished with the reactor.
Parr Instrument Company 4570 HP/HT Pressure Reactors OTHER VESSEL HEAD FITTINGS Safety Rupture Disc There is a safety rupture disc attached to the head which is intended to rupture and release the pressure before it reaches a dangerous level. A metal tag wired to the safety head identifies the burst pressure at room temperature for that particular disc. A similar tag is furnished with each replacement disc.
Parr Instrument Company 4570 HP/HT Pressure Reactors A torque wrench is furnished with these vessels and it includes an adapter for the 12 point heads of the bolts used in these split rings. The amount of torque to be applied will depend upon the intended maximum operating pressure. To ensure a good seal over the full operating range apply the recommended bolt torque per the table below. HOW TO USE THE VESSEL Fixed Head Vessels: First, lower the heater and push it to the side.
Parr Instrument Company 4570 HP/HT Pressure Reactors Releasing Pressure Use the gas release valve to reduce the pressure in the vessel if the reactor is accidentally overcharged when filling. Use this valve also to release any excess pressure during a run and to exhaust the vessel at the end of a run. If the discharge gases are flammable or toxic, discharge to an exhaust hood or to any other safe release point.
Parr Instrument Company 4570 HP/HT Pressure Reactors ACCESSORIES Internal Cooling Coil Spare Parts Kit A serpentine cooling coil is mounted to the underside of the head and sealed with a ferrule and compression nut arrangement. A slow continuous flow of cold water through the coil is an effective means for controlling temperature overshoot, particularly when operating at temperatures below 150 C. Alternately, the cooling coil is used to effectively cool the system at the completion of a reaction.
Parr Instrument Company 4570 HP/HT Pressure Reactors ACCESSORIES (continued) be increased to three drops per minute. If the motor becomes sluggish, flush it with a non-flammable solvent in a well ventilated area. Disconnect the air line and muffler and pour a small amount of solvent into the inlet port. Rotate the shaft by hand in both directions for a few minutes; then connect the air line and run the motor until there is not further trace of solvent in the exhaust.
Parr Instrument Company 4570 HP/HT Pressure Reactors ACCESSORIES (continued) Pneumatic Lift for Fixed Head Vessels For those models equipped with a pneumatic lift package, the following instructions apply: This pressure reactor assembly uses an A2760HC Pneumatic lift package to raise and lower the Cylinder. If needed, It can also be used to raise and lower the Heater assembly.
Parr Instrument Company 4570 HP/HT Pressure Reactors EXPLOSION PROOF OPERATION 3. The Heater The elements in the heater could be dangerous in an explosive atmosphere if the surface temperature of the element becomes high enough to ignite flammable vapors. This hazard must be evaluated for each individual installation since major modifications are required if the heater must be isolated from the surrounding atmosphere.
Parr Instrument Company 4570 HP/HT Pressure Reactors PERIODIC PRESSURE TESTS Each cylinder used in a Parr stirred reactor is tested under hydrostatic pressure to 1.3 times its maximum rating before it is released from the factory. Micrometer caliper measurements are taken during this test to check the deflection of the walls under pressure.
Parr Instrument Company 4570 HP/HT Pressure Reactors GENERAL MAINTENANCE NOTES 1. Periodically inspect all electrical wiring and pressure connections for excessive corrosion. Suspect parts should be replaced by components only supplied by Parr Instrument Company. 2. Always use appropriate wrenches on all fittings and valves. Never use pliers or pipe wrenches. 3. Head and cylinder service fixtures are available for convenience and protection of components during maintenance of your reactor. 4.
